Ω 2 Evaluation-Channel Boundary: Model-Free Local Guard and Halt Tests

This technical note records a model-free local test of a proposed evaluation-channel boundary for Omega 2. The test uses synthetic input, a fake transport, scripted responses, a local guard, an evidence log, and a KIL halt condition. No live provider connection, model invocation, credentials, network request, or external action pathway was used or evaluated. The registered question was: what information, authority, and control pathways may cross between a trusted local preflight gate and a real provider connection while every other pathway remains prohibited? The included executable code tests the local boundary rules only. All 11 registered tests passed within that limited scope. The result does not establish live-provider compatibility, network or operating-system isolation, credential handling, remote model behavior, or safety of a deployed system. The PDF is the technical note. The ZIP package contains the executable Python test, observation record, licensing information, reproduction instructions, metadata, and the formal system diagram. Artificial intelligence tools assisted with research discussion, drafting, code development, and review. Mark Bruce directed the research, formulated the question, defined the boundary conditions, and reviewed the materials and results. The author is responsible for the work and its conclusions.
